There have been a number of threads recently focusing on Vortec heads, what to do with a stock 305, cheap 350 builds, etc. I might well be the only car-building nerd on the Forum, but in case there are others, here is the GM parts list to build your own hydraulic-lifter 350 using GM parts including stock Vortec heads. GM calls this motor a '300HP' crate engine. No idea what the actual dyno output would be. Instead of paying $3000, you can build this from any cleaned up 1-pc or 2-pc 350 block. Probably for well under $2000. The point of sharing the parts list is that you can use GM pieces or cross-reference them to equivalent aftermarket pieces. Many of them could be purchased on or Amazon, if you had the part numbers. Enjoy.

The vortec heads will fit on any good 350. Should be able to find one for under $200 some place and a good set of vortec heads for under $300 and any flat tappet cam with under 480 lift. I would put the price well under $1000 for a build If you do the work your self. I would just find a good used vortec complete motor with the factory hyd roller cam and use a electric fuel pump and it will make well over 300HP in stock form. The heads are the key to the power. Heck their is enough room to through a set of 1.6 rocker on a stock roller cam if you wanted to.
